Unless otherwise defined, all technical and scientific terms used hereinwill have the same meanings as commonly understood by those skilled inthe art to which this disclosure pertains. The terminology used in thedescription of the present disclosure is for the purpose of describingparticular embodiments and is not intended to limit the disclosure. Theterm “and/or” used herein includes any and all combinations of one ormore of the associated listed items.

Referring to FIGS. 1 to 4, where schematic views of an integratedelectronic cigarette according to an embodiment are shown. In thisembodiment, the electronic cigarette includes a main unit 10, acartridge 20, a housing 30, and an auto-eject structure 40. Main unit10, cartridge 20, and auto-eject structure 40 are all disposed withinhousing 30. In particular, main unit 10 and cartridge 20 are disposed attwo ends of housing 30, respectively. Auto-eject structure 40 is locatedbetween main unit 10 and cartridge 20. Housing 30 defines a through hole32 in an end surface of the end where cartridge 20 is located.Auto-eject structure 40 controls the insertion or ejection of cartridge20 into or from through hole 32. Main unit 10 and cartridge 20 arematched with each other. Cartridge 20 can be inserted into housing 30and connected to main unit 10 before the electronic cigarette is readyfor the user to inhale.

Auto-eject structure 40 can control cartridge 20 to be inserted into orejected from housing 30 depending on the user's operation. When needingto smoke the electronic cigarette, the user simply inserts cartridge 20into through hole 32 provided at the end of housing 30 and then pressescartridge 20 such that auto-eject structure 40 would be returned to apreset position and secured thereat. At this point, cartridge 20 isconnected to main unit 10, and so the electronic cigarette is ready forinhaling. In other cases where it is needed to replace cartridge 20 oradd e-liquid, then the user simply presses cartridge 20 at through hole32 such that auto-eject structure 40 would be forced to eject from thepreset position at which it is secured, and then release the forcecartridge 20 would eject out of housing 30 a certain distance. As such,the user can then pull out cartridge 20 by hand.

Referring now to FIG. 3, specifically, main unit 10 includes a battery12, a circuit board 14, a pneumatic switch 16, and a first airflowpassage. Battery 12, circuit board 14, and pneumatic switch 16 areelectrically connected. The inner wall of housing 30 is provided with anintegrally formed frame. The frame includes mounting positions matchedwith the various components of main unit 10, and battery 12, circuitboard 14, and pneumatic switch 16 are all disposed in their respectivemounting positions of the inner wall frame of housing 30. Circuit board14 is provided with conductive columns 18 electrically connected tocartridge 20. Pneumatic switch 16 is in communication with the firstairflow passage to so that during smoking the air flows through thefirst airflow passage and then through pneumatic switch 16. Thus,pneumatic switch 16 is triggered and turned on by the air flow, so thatcartridge 20 is started to work, atomizing the e-liquid for the user toinhale.

Cartridge 20 includes an atomizer assembly, an oil reservoir, and asecond airflow passage. The atomizer assembly includes electrodecolumns, a heating element, and an oil guiding element. The oil guidingelement is wound around the heating element and is in communication withthe oil reservoir. The heating element is coupled to the electrodecolumns, and can produce heat when powered up, thereby atomizing thee-liquid. The electrode columns are matched with conductive columns 18.When the electrode columns are coupled to conductive columns 18, the airflow triggers pneumatic switch 16 to be turned on, causing the electrodecolumns to be electrically connected to conductive columns 18, such thatthe heating element produces heat which atomizes the e-liquid. The firstairflow passage is communicated with one end of the second airflowpassage, while the other end of the second airflow passage is amouthpiece 22. Thus, when smoking the electronic cigarette, the user caninhale at mouthpiece 22 such that the airflow would be driven to flowinside via the first airflow passage and the second airflow passage.During this process, because pneumatic switch 16 is triggered thusactivating the atomizer assembly, what is eventually sucked into theuser's mouth is the airflow accompanied with smoke.

In this embodiment, a one-way silicone valve can further be disposed atthe air inlet of the second airflow passage. When inhaling, the one-waysilicone valve opens due to suction, such that air flows in via the airinlet. If a misoperation is performed, namely blowing at mouthpiece 22,then the one-way silicone valve would seal the air inlet cutting off theair flow between the air inlet and pneumatic switch 16. As such,pneumatic switch 16 is turned off, thereby protecting the atomizerassembly from being burned out and scraped, where the user may otherwiseeven be scalded, because of the misoperation. In addition, theoccurrence of a condensate within cartridge 20 flowing back to circuitboard 14 via the air inlet causing a shirt circuit and damage of circuitboard 14 is also reduced.

Referring now to FIG. 5, in this embodiment, auto-eject structure 40includes an elastic member 42, a movable base 44, a movable support rod46, and a guiding and limiting groove 48. Movable base 44 is disposedbetween main unit 10 and cartridge 20 and abuts against a bottom ofcartridge 20. Elastic member 42 connects housing 30 and movable base 44.Guiding and limiting groove 48 is defined in the inner wall of housing30, and more particularly the housing 30 is integrally formed by way ofdie molding to create guiding and limiting groove 48. One end of movablesupport rod 46 rotatably connected to movable base 44, while the otherend thereof is secured or slides within guiding and limiting groove 48.When cartridge 20 is in the state of being inserted into housing 30,movable support rod 46 is secured at a preset position and is subjectedto a pressure provided by elastic member 42 and guiding and limitinggroove 48 in conjunction. Guiding and limiting groove 48 providedguidance for cartridge 20 and movable support rod 46.

Specifically, the frame of housing 30 further includes a limiting post34 parallel to a running direction of cartridge 20. Movable base 44defines a limiting hole. Elastic member 42 is a spring with one end ofthe spring sleeved on limiting post 34 and the other end inserted intothe limiting hole, and limiting post 34 corresponds to the limiting holein position. When cartridge 20 is pressed by an external force, elasticmember 42 can provide movable base 44 an axial elastic force parallel tothe running direction of cartridge 20, driving cartridge 20 to movesmoothly.

Movable support rod 46 is a U-shaped hook, and movable base 44 defines ahook hole. One end of the U-shaped hook is disposed in the hook hole,and the other end of the U-shaped hook slides within guiding andlimiting groove 48, so that the U-shaped hook can rotate freely withinthe hook hole depending on the forces applied to cartridge 20. In someembodiments, the U-shaped hook deflects by a certain angle from thestraight line in which elastic member 42 lies. When cartridge 20 ispressed to have the U-shaped hook released from the position where it issecured, the U-shaped hook can enter guiding and limiting groove 48according to an expected moving path.

Guiding and limiting groove 48 includes an ejection guide groove 482 andan insertion guide groove 484. Ejection guide groove 482 is disposedparallel to the spring. Insertion guide groove is disposed to bebifurcated with ejection guide groove 482, and an end point of insertionguide groove 484 coincides with a start point of ejection guide groove482 thus forming a motion loop. Ejection guide groove 482 protrudes frominsertion guide groove 484 at its bifurcation with insertion guidegroove 484. In some embodiments, insertion guide groove 484 and ejectionguide groove 482 are bifurcated in a “

” shape. In particular, ejection guide groove 482 and insertion guidegroove 484 are arranged as a trapezoid. The trapezoid is curved at oneof its legs that is closer to main unit 10; that is, the inner wall ofthe guide groove where the curved leg is located is also arranged as acurved slope. One end of movable support rod 46 abuts against the curvedleg, in which case cartridge 20 is placed inside housing 30. To removecartridge 20, cartridge 20 is pressed such that movable support rod 46would slide out of the curved leg, and limited by the curved slope,movable support rod 46 would further slide out of the curved leg to alower base of the trapezoid. Then the forced applied on cartridge 20 isreleased such that the spring supplies an elastic force setting movablebase 44 into motion, which in turn drives cartridge 20 and movablesupport rod 46 to move. As such, movable support rod 46 slides along thelower base of the trapezoid to a preset position. This is the ejectionguide groove 482, in which cartridge 20 is partially ejectedfacilitating the manual removal of cartridge 20. When insertingcartridge 20, cartridge 20 is inserted into through hole 32 and thenpressed to move, and thus movable base 44 and movable support rod 46 aredriven to move. Because ejection guide groove 482 protrudes frominsertion guide groove 484, movable support rod 46 would move alonginsertion guide groove 484. Here, the guiding groove formed by thestraight leg, the upper base, and the partial curved leg of thetrapezoid of insertion guide groove 484 is the insertion guide groove484. Thus, cartridge 20 is pressed driving movable support rod 46 tomove to the curved leg and be secured therein. Then releasing the forcethe presses cartridge 20, cartridge 20 would not pop up.

Returning to FIG. 4, more specifically, the straight leg of insertionguide groove 484 has a design of first flat, then slope, and then flat.The groove heights of the respective running portions of ejection guidegroove 482 and insertion guide groove 484 at the curved leg are alsodifference; in particular, insertion guide groove 484 protrudes fromejection guide groove 482. Thus, when popping up, movable support rod 46would only slide according to a preset ejection trajectory due to theheight difference of the groove surfaces.

Auto-eject structure 40 further includes an elastic pressing piece 49which is fixed to housing 30 and presses movable support rod 46 to staywithin guiding and limiting groove 48. Movable support rod 46 slides inguiding and limiting groove 48, and elastic pressing piece 49 willcreate a certain pressure to movable support rod 46. On the one hand,movable support rod 46 can be prevented from sliding off from guidingand limiting groove 48. On the other hand, the resistance would becomeincreasingly larger in the process of inserting cartridge 20 so that theuser can roughly estimate the insertion status from the force, thusleading to a superior user experience.

In this embodiment, auto-eject structure 40 is a dual-track auto-ejectstructure. That is, guiding and limiting groove 48 and U-shaped hook aresymmetrically disposed on both sides of cartridge 20, respectively, forpurposes of guiding cartridge 20. Thus, cartridge 20 is subjected to asymmetric guidance leading to a relatively uniform force applied tocartridge 20, preventing cartridge 20 from going askew or becomingstuck, which would otherwise adversely affect the ejection or insertionof cartridge 20. Referring now to FIG. 5, more specifically, movablebase 44 is a U-shaped frame movable base. Three sides of the U-shapedframe movable base are all in contact with cartridge 20. That is, theposition of cartridge 20 is restricted on three faces, thereby avoidingthe occurrence of cartridge 20 going askew resulting from the positionof cartridge 20 being restricted on only one face. Thus, the fluency andexperience of use are improved.

Referring back to FIGS. 1 and 2, in this embodiment, housing 30 has aflat shape, and a tempered glass cover 36 is disposed on each of bothsides of the outer wall of housing 30. When viewed from the outside,only the tempered glass covers 36 on both sides and the aluminum alloyframe can be seen, resulting in superior integrity and fashionability.Main unit 10 is further provided with an indicator light 19 connected tocircuit board 14. Indicator light 19 can be disposed on the outersurface of battery 12 or circuit board 14, and then covered by andplaced on the inner side of tempered glass covers 36. Indicator light 19can be a flashing indicator light, and when indicator light 19 is notlit the lighting would not be visible; otherwise when indicator light 19is lit, cool visual effects can be seen from tempered glass covers 36.Tempered glass covers 36 not only have relatively high strength that canmeet the strength requirement for use, but also allow the user toobserve the usage of the e-liquid inside cartridge 20 through temperedglass covers 36, so that it is convenient to add e-liquid or replacecartridge 20 when the e-liquid runs low.

Of course, housing 30 also further defines a hole for mounting acharging port. In particular, main unit 10 is provided with a chargingport coupled to battery 12 for charging battery 12.

The above-described electronic cigarette with cartridge 20 placed insideincludes at least the following advantages.

Electronic cigarette housing 30 is internally provided with auto-ejectstructure 40, which can control cartridge 20 to be inserted into orejected from housing 30 depending on the user's operation. When needingto smoke the electronic cigarette, the user simply inserts cartridge 20into through hole 32 defined in the end surface of housing 30 and thenpresses cartridge 20 such that auto-eject structure 40 would be returnedto a preset position and secured thereat. At this point, cartridge 20 isconnected to main unit 10, and so the electronic cigarette is ready forinhaling. In other cases where it is needed to replace cartridge 20 oradd e-liquid, then the user simply presses cartridge 20 at through hole32 such that auto-eject structure 40 would be forced to eject from thepreset position at which it is secured, and then release the forcecartridge 20 would eject out of housing 30 a certain distance. As such,the user can then pull out cartridge 20 by hand. On the one hand, viewedfrom the outside as a whole, only the housing 30 of the one-piecedesigned housing can be seen, resulting in superior integrity of overallappearance. On the other hand, cartridge 20 is placed within housing 30,which is beneficial to keep cartridge 20 clean, and furthermorecartridge 20 can be removed and inserted simply by a gentle press, whichis simple and convenient, resulting in a superior user experience.
